METHODOF CONVERTINIG'FINEI'COALINTO souo LUMPS.-

Specification forming part of L tors Patent No. 5,739,. dated August '39, 18 48.

f0 all? whom it may concern Be-it known that I, WILLIAM EASJBY. ot' the (city of Washington mm the District of Colum- Aiin, have discoyered a new and useful method of converting line or powdered coulor refuse coal, eitheranthrsci te, bituminous, or charcoal, into solid lumps or blocks orprisms for the use of steam-vessels or any other purppsc in which fuel is required, which method is described as follows: p i

1 take the fine cool and put it into a strong mold ol'i he form and sizeoftheintended blocks,

- lumps,or prisms to be formed, and of suflicient depth to remove the necessary" quantity of line cool. To form the required block, lumps, or prisms and subject the mass to suilicient pressure to cause the particles to adhere and are thntby this process an article ofsmall value and almost useless can be converted into a valuable article of fuel for steamers, forges,

-culinury,-orother purposes, thus saving what is now lost. Thevt'uel thus prepared will be equal to any now in use. It willbe highly admntugeous for steam-vessels, as when formed into-he 'ng'onul prisms it can hestowed in a smaller space than other fuel. It's specific gravity being-greater than that oft-henatural coal will also contribute to this advantage. l or culinary purposes it will have an advantage over unyotheri'uel. 11scompacti' essrcnders it less liable to break or fall to pieces. It is contemplated toform the fuel for the-lastnmued purpose into ovnl or egg-shaped lumps,

thereby leaving no angles to be'worn off by abrasion.

What I chiim as inyinvention, and desireto .secu-rc by Letters Patent, is-- i The formation of small particles of any va riety of coal into solid lumps by pressure, in a il'lzlllllel and for the-purposes suhstuutially as herein described.
